Sneaking out after a training mission, Horde soldier Adora finds an uncanny sword in the Whispering Woods. Princess Glimmer wants it for the Rebellion.

On the run from a monster, Adora, Glimmer and Bow stumble into an ancient First Ones ruin, while the Shadow Weaver orders Catra to bring Adora back.

Glimmer concocts a plan to introduce Adora to Bright Moon, but it all goes wrong. Adora flees into the woods, where she meets an old woman named Razz.

Adora enters the First Ones citadel with Catra on her tail. Inside, they're caught in an illusion simulator that brings back painful memories.

Entrapta's plan to weaken the other runestones allows Catra and Scorpia to attack Bright Moon, but Adora and her friends are ready to fight back.

Force captain Adora wakes up in the Fright Zone alongside her best friend Catra. She's convinced something's wrong, but only Scorpia seems to agree.

Razz confuses the past and the present and has trouble telling Mara and Adora apart. But Adora desperately needs her help.

Adora surrenders herself to Horde Prime, hoping to buy time for Entrapta, Bow and Glimmer to rescue Catra and hack Horde Prime's server.

Shadow Weaver and Catra attempt to reach Adora. Glimmer faces her father while Bow tries to evade Scorpia long enough to execute Entrapta's program.
